Double channel, conditionally dependent components
The monitoring to determine whether a safety guard is open or closed is performed by a pro-
tective switch with lock. One contact is switched by the protective switch, the second by the
lock monitor. If the lock is opened, the guard can also be opened. This sequence of events is
monitored. It is an error if the protective switch opens first.
Which contact is dependent on which can be freely selected in the double channel conditionally
dependent functional device. The dependent contact can be freely opened and closed as long
as the independent contact is not opened.
The functional device for double channel, conditionally dependent components can, thus, be
used for applications such as
• door switch with lock
Here, both the direct connection of an integrated AS-Interface slave as well as the connection
of a conventional device via a safe coupling module are possible.
Double channel, independent components
The monitoring to determine whether a safety guard is open or closed is performed by a pro-
tective switch with lock. One contact is switched by the protective switch, the second by the
lock monitor. With this functional device, it is possible to open and close the lock without forcing
the guard to open or close.
The functional device for double channel independent components can, thus, be used for ap-
plications such as
• protective switch for door monitoring
Here, both the direct connection of an integrated AS-Interface slave as well as the connection
of a conventional device via a safe coupling module are possible. Local acknowledgement
and/or the startup test are available as options.
Note
These components are only available for the types of the AS-Interface safety monitor with en-
hanced function range (type 3 and type 4).
Notice
As a result of the permissible, independent actuation, a loss of redundancy is not detected!
